1998
AUMEGO brand focuses on the manufacture of transmission-specific products in the field of radio and television, including TV differential frequency converters, modems, unidirectional bidirectional amplifiers, and branch distributors.
The first "isopotential" processing technology was successfully developed. The lightning protection effect of products developed with this technology has nothing to do with the size of the grounding resistance (that is, lightning-proof ground wire technology). At the same time, it began to be commercialized for the national broadcast and television industry.
Obtained the first utility model surge arrester in the country, “Practical Model Patent ZL 98 2 35000.7”.
In November, "Isopotential" treatment technology won the "Guangdong Major Scientific and Technological Research Achievement" award.
In December, the Australian and American high-altitude "AL-20K" arrester was rated as "Guangdong Provincial Key New Product".
In December, the products manufactured by the isoelectric lightning protection technology had passed the quality control of the Beijing lightning protection detection agency.

The lightning protection products of the sub-machines of the three-level network have passed the certification of "Quality Supervision and Inspection Center for the Protection Performance of Communication Products of the Ministry of Information Industry".
In 2005
Launched digital TV two-way transmission network lightning protection solutions and product services.
In 2007
Beijing Zhongnanhai issued instructions to the Guangdong Provincial Government Office, and the Zhongshan Municipal Government Office was responsible for auditing the Ao Mei Gao brand. After strict selection, the Ao Mei Gao brand was finally provided with lightning protection products for the communications equipment of the "China Global Embassy" At the same time, the Australian and US sorghums have entered Beijing Zhongnanhai twice.
Year 2008
Began to develop and launch PHS lightning protection solutions and supporting products with provincial telecommunications branches; 4 provinces including Shandong, Fujian, Guangdong, and Guangxi were basically installed.
year 2010
Began to develop and launch lightning protection solutions and professional supporting products for security monitoring systems such as Safe City, Skynet Project, and road bayonet.
2012
Participated in the provincial power branch to develop and launch a lightning protection solution and supporting products for the automatic power meter reading system.
year 2013
Developed the first lightning strike counter for lightning-free ground wires.
2015 year
Introduced the auto-reclosing leakage protector, which can automatically restore the power supply after tripping.
2016 year
Introduced an integrated design lightning protection power supply, which provides lightning protection for the total power supply of front-end monitoring equipment and AC24V, DC12V power supply.
2017 year
Developed a new generation of "DDW equipotential" lightning-free ground wire technology. Based on the original device, the lightning absorption energy has increased by 20%, and the protection level has dropped by less than 22%.
2018 year
Based on the function of the original auto-reclosing leakage protector, it has a lightning protection function for "output terminal equipment". The two-in-one design of lightning protection and automatic reclosing reduces the occupied space.



the difference
Lightning arrester (SPD lightning protection module) VS lightning arrester (DDW equipotential)
Lightning protection principle
Release lightning current to the earth Instantaneously balance the voltage so that the potential between the two lines is equal
Whether to ground
Need to connect lightning protection ground wire, standard resistance value of lightning protection ground wire is 1-4Ω No lightning protection ground wire is required, and the lightning protection effect has nothing to do with the ground resistance.
Environmental limitations
Environments that are not suitable for ground breaking construction, such as floors, squares, and roads, and those with dry or sandy soil layers, fail to meet the standards for installing lightning protection ground lines, making the overall lightning protection effect worse. Limited by the environment In terms of installation and use, it is not limited to any geographical environment
Construction time
It takes half a day to 1 day to install a standard lightning protection ground wire It takes about 10 minutes to install the lightning protection device
Maintenance situation
After two years, professionals must be hired every year to use professional equipment to test whether the ground resistance of the ground wire maintains the original standard and check whether the lightning arrester has failed. Maintenance-free
Stable manifestation
Lightning protection effect becomes worse as the ground resistance changes The lightning protection effect has nothing to do with the ground wire, so the lightning protection effect is relatively stable
Product life
Due to the use of ground discharge current to achieve lightning protection, the potential difference is large, so the lightning arrester has a large loss. Generally, the loss is severe and the service life is shortened after 1-2 years of use. Due to the use of instantaneous balanced voltage to achieve lightning protection, the potential difference between the two wires is small, so the loss of the lightning arrester is small, and it can generally be used for more than 3 years, even as long as 8-10 years.
Faithful protection
Because there is only a parallel connection method, there is a failure indication after the lightning arrester is damaged. When the lightning strike reappears, the equipment can no longer be protected, and it will not be discovered until the equipment is damaged. The lightning arrester is designed with two wiring modes, parallel and series. When using the serial mode, the lightning arrester will be automatically disconnected from the external line when it is damaged, so as to block the frequent lightning current, and to achieve complete protection and prevent equipment from being damaged by lightning.
Low voltage lightning protection
When the lightning current passes through the 4Ω ground wire, a certain voltage value will be generated. The voltage value depends on the magnitude of the lightning current but it must not be equal to 0V. For example: the voltage of low-voltage electronic equipment is 12V, the protection startup voltage of the lightning protection device is assumed to be 15V, and the residual voltage value generated by the lightning current through the lightning protection device to the ground line is assumed to be 100V, then there will be more than 115V of lightning at this moment. The voltage reaches the low-voltage electronic equipment and the equipment is damaged, so the lightning protection effect is not ideal. The lightning protection effect has nothing to do with the ground wire. It adopts the instantaneous balanced voltage lightning protection method to make the potentials between the wires (including the ground wire) equal, so that no residual voltage will flow to low-voltage electronic equipment. .
project costs
Lightning arrester's own cost + lightning protection ground line engineering cost Lightning arrester itself

Australia and the United States focus on the system's lightning protection in the public construction field, around the security monitoring system, cable television system, telecommunications operator wireless network, automatic power meter reading system, traffic road bayonet system and other operations to ensure safety and stability. Continue to innovate and provide intelligent lightning protection power supply system solutions for safe cities, provide reliable and stable guarantees for network transmission systems of operating units, reduce operating costs and improve maintenance work efficiency.
